No OS/browser combo has more than 17% share. And there are five
with more than 10% share. iPhone is about 6% and iPad is about
4%. If you go down to the next ten combos, you find a number of
Android and Blackberry combinations.

Mobile OS/browser combos in total add up to about 15% of all
visits and that number is up from less than 5% a year ago.

Add in the need to build mobile apps for iOS, Android, and
possibly Blackberry and you've got quite a difficult environment
for developers these days.
